(((Debbie))) I completely understand what you are going through as I my tests showed a drop in IQ. I took that pretty hard as I knew something wasn't right. However, the neuropsych told me I have trouble encoding and recalling information and slow processing. I still have a high IQ but notice the changes quite a bit. Just something to keep in mind.
Hockey is right - it is the other traits we have that are much more important. Kindness, compassion, etc. mean far more to me and those around me than a high IQ.
Hang in there and know that you are not alone in this.
